Abstract

We report for the first time, the performance of black pearl (BP) carbon as an electrocatalyst in all-vanadium redox-flow-batteries. Our results show significant suppression in peak potential separation (faster in kinetics than CNTs), 17% improvement in energy efficiency (when compared with CNTs) and good activity retention after 800 potential cycles.
